The issue with Magnetically levitated feet on a TT in my view is that if the motor is separate from the TT then it compromises the rigidity between motor pulley and platter/bearing. I have no doubt that IF one has a TT that is being subjected to vibration and feedback then it may appear to be an improvement in noise floor, however this is at the cost of speed stability. Any vibration from the floor will affect the motor and platter/bearing differently resulting in instability.
An example is my back up TT - Platine Verdier. When I removed the suspension ( which is quite lossy in standard form ), the level of belt creep and oscillation was dramatically reduced - visually around 95% plus and speed stability improved.
In an ideal world the motor and platter/bearing should be rigidly coupled. You might be better to put the TT with motor drive on a platform, and then put the whole platform on the maglev feet if you have feedback issues.
On the subject of the magnetically levitated platter, I use the ball insert on the Verdier ( I can measure the platter lifting down to less than a micron through the use of a dial gauge calliper when the bearing spindle is adjusted such that most of the platter weight is still carried by levitation ). Grounding the bearing tightens up the bass and provides better timing and coherency, and cleaner transients with less smear.
